By typing the question not handwritten -
State the following for the equations which form the foundation of electromagnetic phenomena that will led to Maxwell’s equations
- Law
- Equation
- Physical Interpretation
1)first law gausss law
divergence of electric field= volume charge dnsity / relative permitivity
this law applies when system posses some symmetry
2)faradays law
curl of electric field= negative of partial derivative of B with respect to t
ie a change in magnetic field creates electric field and vice versa
3)divergence of magnetic field = zero
it shows thee non existence of magnetic monopoles
4) curl of magnetic field = relative permeability(J+Jd)
it interprets the existence of displacement current and change in electric field creates magnetic field
